I agree. You can build a simple one without spending much money. 2x4's and 3x8' polycarbonate panels (translucent on the roof, clear on the sides), screen/aluminum door, and perhaps a few pre-hung windows (used ones work fine), and you have a very functional greenhouse. You might even find the 2x4's, door, windows, and polycarbonate/acetate/fiberglass panels at a discount or salvage place. My first greenhouse was built when I lived ont he Gulf Coast was huge and beautiful, a whopping 14x34', made of glass, marine aluminum and brick. I won't even go there when putting a cost on it. It was partially destroyed by two hurricanes and rebult each time. I no longer lived on the Gulf Coast when Katrina hit, but Katrina took it all away, right down to the foundation, and the home-owner did not rebuild it. When I moved up to Starkville, MS, in 1995, I built my own greenhouse, using the materials listed above. It also had three pre-hung windows and a screen door. Not too pretty but quite functional. It was 8x12'. I have now moved again (2010), still in the same neighborhood, and have two 10x12' greenhouses, built from kits. A lot better looking than the home-made one, but of course much more expensive. Ken
